java.lang.Objectnetscape.ldap.LDAPConnSetupMgr
Makes a connection to a server from a list using "smart" failover. Connection attempts can be made serially from the same thread, or in parallel by creating a separate thread after the specified delay. Connection setup status is preserved for later attempts, so that servers that are more likely to be available will be tried first.
The total time spent opening a connection can be limited with the
ConnectTimeout
property.
When a connection is successfully created, a socket is opened. The socket is passed to the LDAPConnThread. The LDAPConnThread must call invalidateConnection() if the connection is lost due to a network or server error, or disconnect() if the connection is deliberately terminated by the user.
